This invention relates to hooks and has for its principal object the provision of an improved keeper device for hooks which may be utilized to prevent the hook from being disengaged from the device with which it is connected.

In carrying the invention into practice, I provide the tip of the hook with a pivotal keeper which may be disposed in a position in unobstructing the throat of the hook or transversely of the throat to obstruct the same so as to prevent the hook from disengagement with the device with which it is connected.

The construction of the hook and keeper is 15 such that when the latter is in obstructing position it is securely held from pivotal move ment.

One form which the invention may assume is exemplified in the following description 0 and illustrated by way of example in the accompanying drawings, in which:

llig. 1 is a perspective view of a hook embodying the preferred form of my invention. 5 Fig. 2 is a view in elevation of the same showing the tip in section.

Fig. 3 is a sectional view through the hook at the throat showing the manner in which the keeper is connected therewith.

lleferring more particularly to the accompanying drawings, indicates a hook of preferred design and proportions including the usual shank 11, throat 12 and tip 1 1. At one side, the tip is formed with a recess which extends at right angles to the throat and across the entire face of the tip. This recess is indicated by the numeral 15.

Extending through the tip at right angles to the recess 15 is a bore 16. The end of the bore opposite the recess 15 is counter-bored as at 17, which is most clearly illustrated in Fig. 3.

Connected with the tip is a keeper 18 which consists of two parallel latch members 19 which are rigidly connected together at one end by means of a pin 20 which extends through the bore 16. The distance between the adjacent faces of the latch fingers 19 is 0 just slightly greater than the thickness of the tip so as to permit movement of the keeper in SAFETY HOOK 1931.

a direction parallel to the axis of the pin 20. An expansion spring 21 is arranged in the counterbore 17 and normally urges the keeper in a direction maintaining one of the latch fingers 19 in engagement with the recess 15. It will be noticed that the portion of the latch finger 19 which engages with the recess 15 is substantially the same in dimensions and contour as the recess 15, so thatwhen it is engaged therewith the keeper will be latched in a position obstructing the throat 12.

To use the hook, if it is desired to connect thesame with a wire or other device, the keeper is moved latterly of the hook in a direction compressing the spring 21 so that the latch finger 19 will disengage from the recess 15. The keeper 19 may then pivot in the bore 16 so as to enable it to be moved to a posltion unobstructing the throat 12.

When it is desired to place the keeper in obstructing position relative to the throat 12, it is only necessary to move the keeper to th s position and when the latch finger 19 aligns with the recess 15 the spring 21 will move the latch finger 19 into engagement with therecess and thereby latch the keeper in posit on obstructing the throat of the hook.

It is obvious from the drawings that when the keeper is in this position it extends transversely of the throat and will prevent the keeper from being disengaged from the device with which it is connected.

From the foregoing it is obvious that I have provided a very simple and efficient safety device for hooks, which device is of simple construction, and while I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the in- 96 vention, as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters latent 1s:

1. A hook of the character described comprising the usual shank and tip with a throat intermediate the same, a keeper member pivotally connected to the tip and capable of extending transversely of the throat to obstruct the same, said keeper being capable 100 of pivotal movement whereby it may be moved 7 to a position obstructing or unobstructing the throat, and complementary latching parts on the tip and keeper for latching the keeper in a position obstucting the throat.

2. A hook of the character described comprising the usual shank and tip, atubular member comprising a pair of spaced fingers,

a pin extending between the fingers at one 7 end thereof and rigidly connecting the same, said tip having a bore therethrough through which said pin extends the. distance between, the adjacent faces of said fingers being slightly greater than the thickness of the tip, said tip having a recess formed in one side thereof, the adjacent fingers being engageable with said recess, and when so engaged be held'in a position transversely of the throat, spring means constantly tending to 1 maintain engagement between said fingers andsa d recess by en'ablingthe keeper to be moved to disengage the fingers from therecess so as to enable pivotal movement of the keeper to move it to an unobstructingposi- A tion relative to the throat. r V
